I'm planning to buy amd radeon 7870 video cards, and use it for dual monitor setup. You know there is a feature of 7th series videocard called Zerocore power, which cuts power consumption to 3 Watts and stops video card fans after screen is blanked after a period of inactivity. It works with dvi conncetion only.
So my question if it works for multi monitor setup (extended desktop mode) where the primary monitor is connected via DVI, and the second one via hdmi. When the screen gets blank will the video card will activete the zerocore mode? Did anyone tried it?
